WPF依赖注入IHostApplicationLifetime关闭程序

WPF依赖注入IHostApplicationLifetime关闭程序

使用Application.Current.Shutdown();退出会报异常 应该使用 app.Dispatcher.InvokeShutdown();

Application.Current.Shutdown();

 app.Dispatcher.InvokeShutdown();

    static App app = new();[STAThread]public static void Main(){_host.Start();using (var scope = _host.Services.CreateScope()){var services = scope.ServiceProvider;var context = services.GetRequiredService<MyContext>();context.Database.EnsureCreated();var appLifetime = services.GetRequiredService<IHostApplicationLifetime>();appLifetime.ApplicationStopping.Register(OnStopping);// DbInitializer.Initialize(context);}app.InitializeComponent();app.MainWindow = _host.Services.GetRequiredService<MainWindow>();app.MainWindow.Visibility = Visibility.Visible;app.Run();}private static void OnStopping(){app.Dispatcher.InvokeShutdown();// Application.Current.Shutdown();// 会报异常}
